Sorry I had to tease the members a little. As alot of you members know that when it comes to me things that apprear to be normal are not. I took a lot of time to figure this one out. How can I make a manifold appear stock but still flow big? Is there more of the maddness to be mod for this manifold yes, I will show you the elbow and the egr throttle valve( I have 2004.5 ) I will save that for a later time on this post, you think the manifold is different wait till you see the other stuff. So way am I doing this? well I like to look stock apprearing and not be. I want all the power and then have someone ( cummings, duramax, and others) look under the hood and say "how the hell is this guy making all this power looks like stock 6.0 powerstroke"
Well anyway here's the real deal inside the manifold that you can't see and how I did it. You can call it stealth MTW manifold, will it flow big? I hope so, better than other manifolds out there? Don't know, but I do know it will flow better than stock for sure. Take a good look at the pictures, I did alot of mods to the inside of manifold, notice the bottom runner it is smooth from the neck, yes I filled all the voids and grounded from inside, while keeping stock look. I went from the bottom of manifold to the neck one side at a time to keep everything stable. EGR bun gone, alternator bracket voids filled and smoothed. I also wanted to keep the coolant to flow like stock. Yes I will be using stock bolts with special washer that seal, I don't think that the bolts will proved that much of a resitiction in flow, main thing is to get the air to the back ports. Hope you like the pictures, I have to put them on two post.
